CANARY IN THE INTERNET MINE WHO IS THIS TALK FOR? FOLKS WHO: make - PowerPoint PPT Presentation

BROOK SHELLEY CANARY IN THE INTERNET MINE

WHO IS THIS TALK FOR? FOLKS WHO: ▸ make applications or websites that you visit in a browser. ▸ launch a new versions - even a minor one. ▸ need to respond to a downtime page. ▸ ever make mistakes. THIS IS FOR YOU

EVERYONE SHOULD BE ABLE TO RELEASE CODE. If a dev deploys code on your infrastructure, 
 but no one can see it, does it matter?

TEXT IT’S COOL, THERE’S A CHANGELOG brook (me)

* Please note no birds were harmed while writing this talk CANARY? YES, PLEASE.

TERMS ▸ Blue/Green: ▸ two production environments as identical as possible. usually, only one is live at a time. ▸ Canary: ▸ testing term originally referring to live canaries used to check for dangerous gasses in mines. ▸ in tech: server/service/deploy dies, there’s problems.

CANARY ▸ A small portion of live traffic. ▸ Testing in production. ▸ If the release dies, abandon that route. 😱😱😱 ☠

CURRENT STATE ▸ Your app is a monolith or maybe microservicces ▸ QA & Testing are expensive. ▸ Things still break. ▸ Rolling back your code takes ⏱ & costs 💱 .

99 SERVICES, 99 PROBLEMS? ▸ Each service or endpoint runs as a microservice. ▸ Incremental release of your application is possible. ▸ Combine with canary releases for success. ▸ Release or roll back service by service.

MONITOR ▸ Early. ▸ Often. ▸ Customer focused metrics.

INDIVIDUAL SERVICES ▸ Per-endpoint/per-service testing. ▸ Measure often - metrics. ▸ Take immediate action. ▸ Stop ruining weekends.

HOW DO WE GET THERE? IT SOUNDS HARD.

PROXIES & ROUTING.

Blue/Green Releases

DEMO TIME.

WRAP-UP ▸ Per-endpoint/per-service releasing. ▸ Measure often with user-centric metrics. ▸ Routing makes roll-back easy and quick. ▸ Stop ruining weekends. ▸ Developers triage at their leisure.
